In nature, then the normal bacteria will grow together several strains for separation and characterization of bacterial types, each species will be a process to make fuel, pure (pure culture) by the spread plate technique is easy to do this technique, in which bacteria are dilute, there are approximately 100-200 cells or less will now be positioned in the middle of the Petri dish (petri dish/plate) and then perform the mediation with the Spectra L shaped glass rods after curing at the appropriate temperature and time enough to appear, the colony (colony) of PHI.Rhea up. Each colony would have a number of bacteria are many and each colony is considered to come from a single species of bacteria. It will then cause the microbes into a pure fuel up. When viewed with the naked eye, each species of bacteria colonies will have different characteristics, as shown in Figure 1-1 can also cause infection are greater purity by taking the colonies to raise in a Petri dish with a new technique called Streak-Plate Technique.
